One more thing to consider: Though I am not sure what the situation is with rotation sites (your last 1.3 years in school) if you go to UCSD:
At UCSF, in your last year, you may not be living in SF, because there are various rotation sites throughout CA that you can be assigned to, as far south as San Diego and as far inland as Fresno and Davis, so for your last year+ 2 months, you may be doing your rotations in a completely new city...
